'New Super Mario Bros U' challenge mode, features detailed

Challenge mode will give players specific conditions to complete levels. They will fall under five categories including time attack, coin collection, 1-up rally and special miscellaneous challenges for single players, and boost mode challenges for two players.

Boost mode challenges will let one player use the Wii U GamePad; they can draw special boost blocks onto the level to help players collect hard to reach coins.

Some examples of challenges include finishing a level without collecting a single coin or finishing without touching the ground. The game will record your successful challenge runs as videos, which can be shared with friends.

There will also be a new coin battle mode, allowing up to four players to compete for who can collect the most coins on a given stage.

There will even be special levels for coin battle mode, where a player can draw and save their own coin layouts using the Wii U GamePad.

New Super Mario Bros U will hearken back to the SNES classic Super Mario World for its world map, using a single overworld map for the entire game rather than breaking each world into its own map.

The more open world map will allow for levels with multiple exits to unlock new secrets and alternate routes for a less linear level progression.
